Audacious (S122)

Events

Keel Laid by Secretary of State for Defence, and Barrow in Furness MP, John Hutton with the new Flag Officer Scotland, Northern England and Northern Ireland Rear Admiral Martin Alabaster representing the First Sea Lord.

HMS Audacious emerges from the Devonshire Dock Hall for the first time.

Will Blamey, BAE Systems Submarines Managing Director, said: "Today's launch marks an important milestone in the Astute programme. Audacious enters the water in a more advanced state of build than any previous Astute class submarine, which puts us in a good position for the next phase of work - the testing and commissioning of her complex systems.

Designing and building a nuclear-powered submarine is extremely challenging and today's launch is yet another reminder of the unique skills required to deliver such complex programmes. It is a proud day and we now look forward to working alongside Audacious' crew to prepare her for sea trials, before she joins her sister submarines in service with the Royal Navy."

Audacious completed its first dive at Devonshire Dock over a two day period
